A Study of Bonviva (Ibandronate) in Women With Post-Menopausal Osteoporosis Previously Treated With Bonviva

Double-blind, Partially Randomized, Parallel Group, Multicenter Study to Assess the Efficacy and Safety of 100 mg and 150 mg Monthly Oral Ibandronate in Women With Postmenopausal Osteoporosis Having Completed the Phase III Oral Ibandronate Trial BM16549

This 2 arm study will assess the long-term efficacy and safety of oral treatment with 100mg or 150mg Bonviva in women with post-menopausal osteoporosis who have previously completed Bonviva study BM16549 (MOBILE study). Patients will receive Bonviva either 100mg po monthly, or 150mg po monthly. Patients will also receive daily supplementation with vitamin D and calcium. The anticipated time of study treatment is 2+ years, and the target sample size is 500+ individuals.

Absolute change from Baseline in mean BMD of the lumbar spine (L2 - L4) measured as grams per square centimeter (g/cm^2). This was baseline of Study MA17903 after two years of treatment in the core study (BM16549 [NCT00081653]).

BMD was measured by a single dual-energy X-ray absorptiometry (DXA) scan of the lumbar spine (BMD of at least 2 vertebrae [L2-L4] that were not fractured and not affected by osteoarthritis to such a degree that BMD measurement would be compromised) at the time of enrollment and at Months 12, 24 and 36. This was baseline of Study MA17903 after two years of treatment in the core study (BM16549 [NCT00081653]).

BMD was measured by a single DXA scan of the hip. Scores between -1 and -2.5 indicate Osteopenia (thin bones). Less than -2.5 indicate Osteoporosis (porous bones).

CTX is a measure of bone resorption and is measured as ng/mL. Blood samples for the Month 6 values were collected 6 days after the 6-month dose; therefore, the Month 6 values are not true 'trough' values.
